Description

Technical Field

[0001] This utility model belongs to the field of needle coke processing technology, and specifically relates to a needle coke calcination device. Background Technology

[0002] Needle coke is a high-quality carbon material that is being vigorously developed. It is a porous solid with a silvery-gray appearance and a metallic luster. Its structure has obvious flow texture, with large and few pores that are slightly elliptical. The particles have a large length-to-width ratio and a fibrous or needle-like texture. It feels smooth to the touch. It is a raw material for producing high-end carbon products such as ultra-high power electrodes, special carbon materials, carbon fibers and their composites. In the processing of needle coke, it needs to be calcined.

[0003] In the existing technology, a certain amount of smoke and dust is often generated when needle coke is calcined. The smoke and dust emitted will cause workers to inhale a lot of raw coke dust, which will cause physical discomfort and pollute the environment of the factory workshop. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a needle-shaped coke calcination device.

[0005] To achieve the above objectives, this utility model provides a needle coke calcination device, including a calcination tank, wherein the calcination tank has an inlet and an outlet at the top and bottom respectively, a support foot is fixedly connected to the outer wall of the calcination tank, and a purification mechanism and a limiting mechanism are provided on the outside of the calcination tank.

[0006] The purification mechanism is used to adsorb the smoke and dust generated during calcination;

[0007] The limiting mechanism is used to improve the stability of the purification mechanism during use.

[0008] In the above technical solution, the purification mechanism further includes a conduit and a protective net, the protective net being fixedly connected above the calcining tank, the conduit being connected to the top of the calcining tank, and the protective net being located inside the conduit.

[0009] In the above technical solution, the end of the conduit is further connected to an installation box, the installation box is fixedly connected to the outer wall of the calcining tank, the interior of the installation box is rotatably connected to a rotating frame, the interior of the rotating frame is equipped with an activated carbon plate, the interior of the installation box is provided with an arc-shaped groove, and the interior of the installation box is equipped with a fan.

[0010] In the above technical solution, a first spring is fixedly connected inside the rotating frame, and a locking block is fixedly connected to the end of the first spring. The locking block is slidably connected to the rotating frame and is engaged inside the arc-shaped groove. A handle is fixedly connected to the middle of one side of the rotating frame, and a round hole is opened in the middle of the handle.

[0011] In the above technical solution, the limiting mechanism further includes a fixed block, and a sliding rod is slidably connected inside the fixed block, with one end of the sliding rod being engaged inside the circular hole.

[0012] In the above technical solution, further, a limiting block is fixedly connected to the outside of the sliding rod, one of the limiting blocks is located inside the fixed block, and the other limiting block is located outside the fixed block.

[0013] In the above technical solution, a second spring is sleeved on the outer wall of the sliding rod, the second spring is located inside the fixed block, and a handle is fixedly connected to one end of the sliding rod.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] In this invention, the smoke and dust generated during the calcination of needle coke can be adsorbed by activated carbon plates, thereby purifying the environment around the calcination tank. After prolonged use, the activated carbon plates can be flipped and positioned so that the back side is positioned below the conduit, fully utilizing the relatively surplus adsorption space on the back side of the activated carbon plates and improving their utilization rate. 2. In this invention, the operator can pull the sliding rod via the handle to slide it along the outside of the fixed block. During this process, the limiting block inside the fixed block compresses the second spring. The second spring, after being compressed, undergoes elastic deformation and stores a certain amount of elastic potential energy. After the operator rotates the handle 180 degrees, the handle can be released. At this point, the second spring, in its elastic deformation state, will rebound, causing one end of the sliding rod to engage inside the round hole, thus limiting the handle and preventing the rotating frame from rotating inside the installation box due to external impact.

[0025] Example 1

[0026] like Figure 1 - Figure 5The device shown is a needle-shaped coke calcination apparatus, including a calcination tank 1. The calcination tank 1 has an inlet 11 and an outlet 13 at its upper and lower ends, respectively. Support legs 12 are fixedly connected to the outer wall of the calcination tank 1. A purification mechanism 2 and a limiting mechanism 3 are installed on the outside of the calcination tank 1. The purification mechanism 2 is used to adsorb the smoke and dust generated during calcination. The limiting mechanism 3 is used to improve the stability of the purification mechanism 2 during use. The purification mechanism 2 includes a conduit 21 and a protective net 22. The protective net 22 is fixedly connected to the top of the calcination tank 1. The conduit 21 communicates with the top of the calcination tank 1. The protective net 22 is located inside the conduit 21. The end of the conduit 21... The installation box 23 is fixedly connected to the outer wall of the calcining tank 1. The installation box 23 is rotatably connected to the interior of the installation box 23. An activated carbon plate 291 is installed inside the rotating frame 25. An arc groove 24 is opened inside the installation box 23. A fan 292 is installed inside the installation box 23. A first spring 27 is fixedly connected inside the rotating frame 25. A locking block 26 is fixedly connected to the end of the first spring 27. The locking block 26 and the rotating frame 25 are slidably connected. The locking block 26 is locked inside the arc groove 24. A handle 28 is fixedly connected to the middle of one side of the rotating frame 25. A round hole 29 is opened in the middle of the handle 28.

[0027] In this embodiment, when the fan 292 is started, it will generate a suction force. The smoke and dust generated when the needle coke is calcined in the calcining tank 1 will pass through the protective net 22 and enter the interior of the conduit 21. Subsequently, it will be adsorbed by the activated carbon plate 291. After the activated carbon plate 291 has been used for a long time, there will still be relatively abundant adsorption space on the side away from the conduit 21. If it is necessary to rotate and flip the activated carbon plate 291, the operator can rotate the handle 28. After the handle 28 is rotated, the rotating frame 25 will rotate with the handle 28. During this process, the inner wall of the arc groove 24 will squeeze the locking block 26. After being squeezed, the locking block 26 will slide along the direction inside the rotating frame 25. The first spring 27 will also undergo elastic deformation and contraction and store a certain amount of elastic potential energy. After the rotating frame 25 has completed a 180-degree rotation in the mounting box 23, the locking block 26 will re-lock into the interior of the arc groove 24, thereby completing the limitation of the rotating frame 25 inside the mounting box 23.

[0028] Example 2

[0029] like Figure 1 - Figure 5The device for calcining needle-shaped coke shown includes a limiting mechanism 3 comprising a fixed block 31, a sliding rod 32 slidably connected inside the fixed block 31, with one end of the sliding rod 32 engaged inside the circular hole 29, and a limiting block 34 fixedly connected outside the sliding rod 32, one limiting block 34 located inside the fixed block 31 and the other limiting block 34 located outside the fixed block 31, a second spring 33 sleeved on the outer wall of the sliding rod 32, the second spring 33 located inside the fixed block 31, and a handle 35 fixedly connected to one end of the sliding rod 32.

[0030] In this embodiment, the operator can pull the sliding rod 32 with the handle 35 to make the sliding rod 32 slide along the outside of the fixed block 31. During this process, the limiting block 34 located inside the fixed block 31 will compress the second spring 33. After being compressed, the second spring 33 will undergo elastic deformation and contraction and store a certain amount of elastic potential energy. After the operator rotates the handle 28 180 degrees, the handle 35 can be released. At this time, the second spring 33, which is in an elastic deformation state, will rebound, thereby driving one end of the sliding rod 32 to engage inside the round hole 29, so as to complete the limiting of the handle 28 and avoid the problem of the rotating frame 25 rotating inside the mounting box 23 due to the impact of external force on the handle 28.

[0031] Working principle: The operator can put the needle coke raw material to be calcined into the calcination tank 1 through the feed inlet 11, then calcine it, and finally collect the calcined needle coke through the discharge outlet 13. The smoke and dust generated during the calcination process will pass through the protective net 22 and enter the inside of the guide tube 21, where it will be adsorbed by the activated carbon plate 291. After the activated carbon plate 291 has been used for a long time, there will still be relatively extra adsorption space on the side away from the guide tube 21. If it is necessary to rotate and flip the activated carbon plate 291, the operator can turn the handle 28. After the handle 28 is turned, the rotating frame 25 will rotate with the handle 28. During this process, the inner wall of the arc groove 24 will squeeze the locking block 26. After being squeezed, the locking block 26 will slide along the direction inside the rotating frame 25. The first spring 27 will also undergo elastic deformation and contraction, storing a certain amount of elastic potential energy. After the rotating frame 25 completes a 180-degree rotation within the mounting box 23, the locking block 26 will re-engage inside the arc-shaped groove 24, thus limiting the rotation frame 25 within the mounting box 23. Additionally, the operator can pull the sliding rod 32 via the handle 35 to slide it along the outside of the fixed block 31. During this process, the limiting block 34 inside the fixed block 31 will compress the second spring 33. After being compressed, the second spring 33 will undergo elastic deformation and store a certain amount of elastic potential energy. When the operator rotates the handle 28 180 degrees, the handle 35 can be released. At this point, the second spring 33, in its elastic deformation state, will rebound, causing one end of the sliding rod 32 to engage inside the round hole 29, thus limiting the handle 28 and preventing the rotating frame 25 from rotating within the mounting box 23 due to external impact.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this utility model.
